You can put this solution on YOUR website!
There is obviously no solution,
\n" ); document.write( "because $\"x-y\"$ cannot equal $\"4\"$ and equal $\"13\"$ at the same time.
\n" ); document.write( "By elimination, you would multiply $\"x-y=4\"$ times $\"%28-1%29\"$ ,
\n" ); document.write( "to get $\"-x%2By=-4\"$ ,
\n" ); document.write( "and then add $\"x-y=13\"$ , getting
\n" ); document.write( " $\"-x%2By%2Bx-y=-4%2B13\"$ ---> $\"0=9\"$ .
\n" ); document.write( "so there is no pair (x,y) that will satisfy both equations
\n" ); document.write( "(unless you know of a planet where $\"0=9\"$ ).
\n" ); document.write( " \n" ); document.write( "

\n" );
